What is the value of 100?
Nesterboy [21]

Answer:

10

Step-by-step explanation:

Means back the numbers into multiples of several small numbers

Like:; 1. We take LCM of 40

Just break into multiples of small number

40= 2×2×2×5

2. We take LCM of 50

50= 5×5×2

So LCM for 100 is 2×2×5×5

after that see the pairs in the LCM like 2×2 or 3×3 or 4×4(same numbers)

Then write the the single number in place of two multipled numbers

Like:; 2×2 is written as 2 // 3×3 is written as 3

So we can write 100 into 2×2×5×5 and then after selecting pairs (2×2)×(5×5)

write pairs in single number 2×5

And so we get 2×5=10

So we find root of 100 that is 10

Solve your equation using trail and improvement. A number plus ten times its square root is is equal to one thousand
Alex

Answer:

x \approx 729

Step-by-step explanation:

Given

Let the number be x

So:

x + 10\sqrt x = 1000

Required

Using trial and improvement, find x

This implies that we keep guessing the values of x until we get a value that match the equation.

Let

x = 625

So, we have:

x + 10\sqrt x = 1000

625 + 10 *\sqrt{625}

Take the square root of 625

625 + 10 *\sqrt{625} = 625 + 10 *25

625 + 10 *\sqrt{625} = 625 + 250

625 + 10 *\sqrt{625} = 875

Let

x = 729

So, we have:

x + 10\sqrt x = 1000

729 + 10 * \sqrt{729}

Take the square root of 729

729 + 10 * \sqrt{729} = 729 + 10 * 27

729 + 10 * \sqrt{729} = 729 + 270

729 + 10 * \sqrt{729} = 999

At this point, we can conclude that x is approximately 729 because

999 \approx 1000

So:

x \approx 729
